Mathematical modeling, coupled with new observations of magnetic susceptibility, yield better estimates of the underground configuration of granite plutons.
Two high-resolution aeromagnetic surveys in south-central Colorado compiled to assess the subsurface geologic framework of the San Luis basin for ground-water flow model construction, and to map concealed faults potentially related to geothermal resources
A fault map and digital fault dataset were constructed based on offsets of the basement surface. Because these
faults are, in large part, not present at the surface, they are interpreted to be inactive faults, older than the alluvial basin fill.
